I lead the spring wheat breeding and genetics program. We are focused on development of biotic and abiotic stress tolerant, high-yielding, and high-quality spring wheat varieties for diverse Washington (Pacific Northwest) production environments. Genetic dissection of disease resistance, grain quality, and abiotic stress tolerance traits are major research areas. Germplasm enhancement, application of genomics information and technology, and appropriate breeding and selection schemes are integrated to strengthen long-term variety development efforts and accelerate genetic gain.
